Does anyone know the position with the gates/validators at Farringdon? A
typical scenario is an occasional journey Brighton to Moorgate and return:

1. I use my National Rail season which is valid as far as City Thameslink.

You are travelling without a valid ticket between City Thameslink and
Farringdon. To combine a paper National Rail ticket and Oyster Prepay
you must touch in where your paper ticket ends, at City Thameslink.


2. At Farringdon I validate the prepay card on the platform (does it matter
which platform I do this on?) and then
3. Change to the Underground for Moorgate.
4. At Moorgate I the prepay card lets me out through the gates.

Prepay requires a touch in and out, so your usual journey is valid
between Farringdon & Moorgate. Just touching out at Farringdon would
lead to an unresolved journey.


Fascinating. So you'd have to get out at CT, go up to the ticket hall
to touch in, then come back down again and get on another train for the
10 second journey to Farringdon?

In this case, yes.

In that case I suppose the Farringdon validators are actually intended
for people changing *onto* Thameslink, having used Prepay to get them
there on the Tube (since otherwise you would be leaving the Tube
without passing through a gateline). In fact I can't think of any way
they could be used in the opposite direction (though I suppose someone
might *theoretically* have e.g. a Brighton - Farringdon LU season...)

Not really... you could have any National Rail ticket valid to
Farringdon (e.g. a single from Luton to Farringdon) and then you would
touch in on the validators with an Oyster in order to continue your
journey on the Tube (e.g. to Whitechapel).
